For those of you that play chess into the wee hours of the morning, Dutch designer Daan Van Tuldur has created a set that is lit by LEDs that are located in the 4 corners of the board. Black and white are replaced by matte and transparent squares, and all the pieces basically have the same shape. Besides this prototype, Van Tuldur has worked on many designs, including HotSpots, arcade-size retro systems geared for the next generation of Atari gamers.

Researchers have developed a flexible battery that can be twisted, bent, or shaped with scissors. The pricey prototype created at Rensselaer Polytechnic Institute is only one piece with carbon nanotubes and an electrolyte embedded in the paper, and is black on one side and white on the other. Professor Robert Linhardt said he would like to “scale this up to the point where you can imagine printing like a newspaper. That would be the ultimate.”

We just hope that the “ultimate” would be a product that we don’t have to worry about being recalled.

The Brush and Rinse Toothbrush on the left features a concave back to create a mini-water fountain to your mouth so that no one will catch you slurping out of the faucet. Although you can purchase one for only $3.00, we understand that there are only 27 original prototypes in existence and that they are available for $1,750.00 each. We took our average toothbrush and attached a measuring spoon to the back with a twist-tie and it worked just fine. We suppose we could let it go for a mere $1,000.00, since our version is a one-of-a-kind and very slightly used.
